.DISCUSSION...

A MUCH WARMER AND DRY DAY WILL OCCUR AS A STRONG RIDGE BUILDS OVER
THE ROCKIES. A WEAK SYSTEM WILL SKIRT WYOMING THIS WEEKEND WHICH
WILL BRING A SLIGHT CHANCE FOR SOME HIGH BASED RAIN SHOWERS AND
POSSIBLY A THUNDERSTORM. THE MAIN CONCERN WITH THIS ACTIVITY WILL
BE GUSTY AND ERRATIC WINDS...BUT A WETTING RAIN IS NOT EXPECTED. A
MAJOR CHANGE IN THE WEATHER WILL OCCUR...MIDDLE TO LATE NEXT WEEK
AS A STRONG STORM SYSTEM MOVES ACROSS THE REGION. ACCUMULATING
SNOW WILL BE POSSIBLE WITH THIS SYSTEM.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
